Katena32 [7]
For this case, the first thing we must do is define a variable.
 We have then:
 x: number of weeks
 y: amount of cereal that Melanie eats
 We now write the function that models the problem:
 y = 1.5x

 Then, for 5 weeks we have:
 y = 1.5 (5)

y = 7.5 pounds
 Answer:

Margaret has 16 yards of fabric and she is making dresses for z doll write the expression for the length of fabric used for each
emmasim [6.3K]
<h3>The expression for the length of fabric used for each doll is \frac{16}{z}\ yards</h3>

<em><u>Solution:</u></em>

Given that,

Margaret has 16 yards of fabric

she is making dresses for z doll

Therefore,

Total length of fabric = 16 yards

Number of dresses = z dolls

Therefore,

\text{ length of fabric used for each doll } = \frac{ \text{ Total length of fabric }} {\text{ z dolls }}\\\\\text{ length of fabric used for each doll } = \frac{16}{z}\ yards

Thus, the expression for the length of fabric used for each doll is \frac{16}{z}\ yards
